Efcore: unable to add migrations

[digounet]

I'm trying to enable migrations on a class library project. But every type I run the command dotnet ef migrations add Initial then I have the No executable found matching command "dotnet-ef" error.

This is my .csproj file:

<?xml version="1.0" encoding="utf-8"?>
<Project Sdk="Microsoft.NET.Sdk" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <TargetFramework>netcoreapp1.1</TargetFramework>
    </PropertyGroup>
    <ItemGroup>
        <PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL">
            <Version>1.1.0</Version>
        </PackageReference>
        <PackageReference Include="Microsoft.EntityFrameworkCore">
            <Version>1.1.0</Version>
        </PackageReference>
        <PackageReference Include="Microsoft.EntityFrameworkCore.Design">
            <Version>1.1.0</Version>
        </PackageReference>
        <PackageReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet">
            <Version>1.1.0-preview4-final</Version>
        </PackageReference>
    </ItemGroup>
    <ItemGroup>
        <ProjectReference Include="..\Organizer.Domain\Organizer.Domain.csproj">
            <Project>{D3276E9C-4A92-47EC-BF15-61EC5B78655D}</Project>
            <Name>Organizer.Domain</Name>
        </ProjectReference>
    </ItemGroup>
    <ItemGroup>
      <Folder Include="EntityConfig\" />
      <Folder Include="Context\" />
    </ItemGroup>
</Project>

Hi there. It looks like your reference to the tools is in the wrong part of the project file. Take the Package Reference to Microsoft.EntityFrameworkCore.Tools.DotNet out and add the below snippet to your project. Also because you are using csproj and not project.json you need to use the 1.0.0-msbuild3-final tooling rather than the 1.1.0-preview4-final that you have in your project.

I hope that helps get you going :-)

    <ItemGroup>
        <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="1.0.0-msbuild3-final" />
    </ItemGroup>
